- A surveyor completes a levelling circuit from a knownBM at point A (RL = 37.730 m). At the end of the survey, thesurveyor finds out that the rod person moved the graduated staffbefore a BS value was taken at the third change point. The levelsobtained are as follows:Â Â
1.857 (RL =37.567 m), (0.983, 0.354), 0.571, 1.011, 2.151, (1.124,x), 0.890, (0.543, 3.178), 3.808. Â
- Assuming that the misclosure for the level circuit is0.000 m, find the probable value of the missing BS valuex. Â Â
- Is the value of x in part (a) acceptable?Explain. (1 mark)
Book the levels, including the value of xcalculated in part (a) using the HPC method and show all arithmeticchecks. (1 mark
